Version 1.2 Stable breaks my health provider site.

I went to my health provider's site to message my doctor. Version 1.2 of Vivaldi breaks the site in several ways. 1) There's a menu bar on the page. Each selected section has a submenu bar below it. The submenu should continue to display. However, 1.2 has the submenu disappearing unless the mouse pointer is over the submenu area. That was not the case with either previous versions of Vivaldi or any other browser. 2) Despite the above, I got to the messages section. Clicking the link to email my doctor, I get an error page that tells me the site has redirected me too many times, Again, this was not an issue for previous versions of Vivaldi and isn't an issue with other browsers.
